CentOS based VM (NethServer) fails to boot (starts the VM but cannot mount volumes inside qcow2 image)!

The issue seems to be UNRAID.

Aside from the attempts I have made (I can provide the details) to recover OS booting, I now tried a fresh install.

(the same I used when I originally set up NethServer inside UNRAID years ago)

The installer crashes, because seemingly of network issues, as it reports "couldn't open file /tmp-network-include".

 

Back on the existing installation, note that the qcow2 image itself is fine, I managed to connect it to UNRAID (host), see the partitions inside (including the lvm partitions root and swap), I managed to mount the root partition and see the files inside.

So the disk image is ok.

 

The problem started right after 6.12 reboot.

Something changed in kvm/libvirt/qemu/uefi that prohibits NS7 from running.

 

NEWER UPDATE which seems to point UNRAID as the probem.

Attempting to install fresh does NOT find any usable disk and does NOT find any usable network!

Seems that with 6.12, CentOS7 does not recognise ANY virtio device!

 

So I changed vdisk to be SATA and network to be e1000 and it works!

Definitely an issue!

Changed Status to Open

Changed Priority to Other

 

Pity nobody actually reacted when priority was urgent.

How is it urgent? There is a workaround.

 

Not a showstopper, data loss, or server crash.

This is why I changed the priority.

But before finding the solution myself, it was urgent at least to me, as NethServer (which is a full small business server, so potentially important to some of us) was not running. No mail etc.
